BD Diesel 17-19 Ford 6.7L 6R140 Stage 4 Transmission and Converter Package

Already running headers and a tuner on your 6.7L Power Stroke? This BD Diesel Stage 4 transmission and converter package is the next piece of the puzzle to handle the increased power and torque. This isn't just a transmission; it's a matched set, dyno-tested together to ensure peak performance and reliability when you need it most. Whether you're towing heavy loads, cruising the street, or hitting the track, this package is built to stand up to the demands of your diesel.

BD Diesel has engineered this package with significant upgrades over the stock transmission. You'll find an increased clutch count across all gears – 8 in the intermediate, 8 in overdrive, 6 in forward, 6 in direct, and 5 in low reverse – providing up to 76% more theoretical holding power. This is achieved through custom BD patented pressure plates and dual surface clutch assemblies, all within a fully remanufactured transmission housing for long service life. The included Electronic Line Pressure Controller can deliver up to 300psi of line pressure at wide-open throttle, but it only activates when boost exceeds 15psi, meaning it doesn't create parasitic load or extra heat when you're not pushing the limits.

The torque converter is also a key part of this matched set, featuring furnace-brazed pump and turbine fins for added durability, making it an ideal replacement for a tired stock converter. This package includes BD's own Heavy Duty pan, which adds extra fluid capacity, helping to keep temperatures down during demanding use. This transmission package is a solid option for anyone looking to reliably put down serious power from their 6.7L Power Stroke.
